Thanks For the casting lesson!Sorry to hear this, 4wings, you must be very disappointed.
There are lots of good videos on YouTube if you've got an itch you can't scratch. I like Jim Green's 'Secrets of Fly Fishing'.
Although it's appearance is dated, Jim Green really did know his stuff and I think explains his casting style very clearly. There are so many to choose from, just surf around until you find one which 'speaks to you'. Grass casting isn't ideal but it's better than nothing if you can get out to a garden or park. Just learning to false cast smoothly is a step in the right direction and you'll find the whole thing easier and more effective when you do manage to get to some water.
